The ceremony was organized by the Vietnam Office for Seeking Missing Persons (VNOSMP).
The remains were discovered by a Vietnam-U.S. joint search team between April last year and July this year.
The remains were examined by forensic experts in Hanoi, who concluded that they are likely to be of U.S. soldiers missing during the Vietnam War. The experts recommended that they are taken to the U.S. Defense POW/MIA Accounting Agency's laboratory in Hawaii for further verification.
The search for missing U.S. soldiers' remains from the Vietnam War, which ended in 1975, has been an ongoing humanitarian activity that Vietnam has engaged in since 1988.
This is the 156th handover of American remains since 1973.
